Because of the low temperature of the effluent, the low temperature chiller is quite different from the conventional chiller in the design of the unit. The most basic difference is the chilled water. The low temperature unit needs to add the appropriate type and the appropriate concentration of antifreeze to ensure the normal operation of the low temperature unit. So, how to choose an industrial cryogenic refrigeration unit?
Since each manufacturer has different outlet water temperatures for low-temperature chillers, there are also many corresponding refrigeration equipment models. Therefore, the following three points should be noted when selecting industrial cryogenic refrigeration units:
1. Can you guarantee the production demand: The choice of cooling capacity is particularly important. If you choose small, you can't meet the production needs. If you choose big, it will cause waste. The enterprise can calculate the cooling capacity through the actual production needs, and after determining the cooling capacity, it is more clear in the selection of the chiller.
2, the choice of cooling mode: low-temperature chillers can be divided into air-cooled low-temperature chillers and water-cooled low-temperature chillers according to the cooling method. These two types have their own characteristics. The air-cooled units are placed outside without the machine room, and the installation is relatively simple; The water-cooled unit needs a machine room, and also needs to be equipped with a cooling tower and a cooling water pump. The installation is relatively troublesome, but the cooling efficiency is high and the operation is more stable.
3, the choice of the number of low-temperature chillers: generally choose 2 to 4 units, the unit should consider the possibility of mutual standby and switching use. In the same equipment room, a combined solution of different types and different capacity units can be used to save energy.
